This is good. A few years ago, spurred by green tech doubters pointing to material shortages, I looked briefly at lithium battery recycling. I found that it was not happening and if lithium was being recovered, it was being used as an additive to concrete, or some such silliness.

Green tech must be able to recycle its materials, both from batteries and power generation equipment (wind generators, solar arrays, ...) If it doesn't, it's really not that sustainable.
